Although I don't mind a few of the new films and found them entertaining (Solo/ROS), for me the sequels and especially the prequels do nothing but diminish the original films.
I occasionally try to watch the prequels and people seem keen to convince me they are any good, particularly Revenge of the Sith. I could tolerate it just being boring, but it's worse than that.
Case in point - Yoda. As a kid I thought Yoda was just really old and not able to fight, and much too spiritual / magical for all of that anyway. I imagined him living on dagobah for most of his life, training Jedis ... Instead, in the prequels he runs a local council badly, does nothing, looks weird, fights in a stupid way, loses, talks in a silly way that is not consistent with the OT, and then goes into exile for no real reason whilst his mates get slaughtered around the universe.
There are literally hundreds of ways the prequels and sequels make the originals worse for me, and whilst I find some of them entertaining, for me the prequels (and expanded universe stuff which just fills in movie plot holes) just taint the originals. I know others love it all and I don't begrudge them, but it's not for me.
